Port-side Trim Tab Doesn(39)t move.-gctid816977

[Bigbryz]

Have Instatrim Boat Leveler system on my Ciera 2455. Port side tab doesn't work. I swapped the Cylinders, and problem remained on port

side. I can hear the hydraulic pump actuate when toggling the switch, but, it doesn't move the tab. So hard to get back to where the pump & Actuators are.

Any ideas how to troubleshoot - maybe from the switches?

Motor runs? The solenoid for that side could be bad. I'd first check/clean all electrical connections at the pump and switch. Sometimes they become corroded and cause issues.
